Abelvattnet

The construction of the power plant was accompanied by measures to improve the safety of the existing dam. Thanks to its reinforcement, the dam can withstand a so-called 10,000 year flood, i.e. an extreme flow of water which is likely to occur only once every 10,000 years.

Fish protection

Lake Abelvattnet is home to a species of lake-spawning trout which must not be mixed with fish from Lake Bleriken. Before the power plant was built, the migration of fish from Lake Bleriken was prevented by a concrete wall. When the hydro power plant was built, a fish barrier was installed in the turbine. The difference in height between the inlet to the power plant and the maximum water level of Lake Bleriken, combined with high water speeds when the power plant is in operation, prevents fish from getting through.
